` s claims. (ci 259-11) This invention relates to sintering machines of the peak of the piles oi the material which has the type which includes a. sintering bed and a formed on thelatter when discharged thereon spout or hopper which depends over this bed so from the spout 4. It follows that the swinging as to distribute the material to be sintered there action of the spout 4- also swings the bar 5 so v 5 on, one of the objects being to improve this type that its extreme end constantly agitates the peak 6 respectingl its ability to properly'handle finely of the-material. This has been found to `be an divided materials, such as flue dust, zinc oxide, important factor in thegprevention oi the formaiine flotation products, etc. Other objects may tion of lumps and in that it provides an assur'- be inferred. i ance that the material will be evenly distributed An example Vof the invention is illustrated by over the slntering bed.l v l0 the accompanying drawingyin which Figure 1 is I` claim: v
